Question

Which of the following dont depend on the orientation of the axes:
1. the value of a scalar
2. component of a vector
3. a vector
4. the magnitude of a vector 
plz explain and not just give ans

jlastino · Answer

1. The Value of a scalar - (Temperature is a scalar quantity and it doesn't have direction)

anonymous · Answer

according to book
ans:1,3,4

jlastino · Answer

3A vector is something that has both direction and magnitude  (Like displacement , it doesn't matter where it is in the xy plane but how far it went from its starting position)
4. The Magnitude is only the amount of force applied so it isn't dependent on the position of the axes.

anonymous · Answer

|dw:1334231665564:dw|
meaning both these vectors are same?

jlastino · Answer

no they are not their values still depend on the forces and direction applied what I am saying is that  they don't use trigonometric functions that depend on the orientation of the axes.
